Jarkko Sakkinen 13b47cfcfc tpm: fix a kernel memory leak in tpm-sysfs.c ... While cleaning up sysfs callback that prints EK we discovered a kernel memory leak. This commit fixes the issue by zeroing the buffer used for TPM command/response. The leak happen when we use either tpm_vtpm_proxy, tpm_ibmvtpm or xen-tpmfront.
